Flexigas typically saves up to 75% of the time required for copper or steel installations. And because it can be bent by hand and passed through interior spaces easily using long continuous runs of tubing. The patented Flexigas fittings ensure a secure seal in a matter of seconds without the need for any specialist tools. No soldering, sealants or heavy crimping tools are required.
How to Install the Flexigas System
Step 1 - Cut
Cut the Flexigas tubing using a wheel metal pipe cutter. Ensure the cut is centered in the valley between corrugations and the cutter is only slightly tightened on each full revolution around the tube. Make sure the cut is clean and circular with no sharp edges.
If a clean, circular cut is not made, or if there are any jagged or sharp edges, a proper seal may not be obtained.
Use a properly sized tubing cutter with a large wheel, especially for larger sizes.
Do not use circular copper tubing cutters.
Step 2 - Remove
With a utility knife, safely remove the flame retardant yellow cover so that the last four corrugations are exposed.
Step 3 - Slide
Slide the nut over the tubing and then place the two semi-circular collets around the tubing so that the ridges on the collets occupy the last three valleys of the tubing.
Step 4 - Tighten
Make sure that the copper ring is in place on the seat inside the fitting before inserting the collets into the fittings. Tighten the nut and fitting using two suitably sized wrenches. The seal is formed when the last corrugation deforms around the copper seat inside the fittings. Use sufficient torque.
Step 5 - Wrap
After conducting a gas tightness test, wrap the small gap between the “tail” on the nut and tube using yellow silicone tape.
